Run, ride, swim, race — together
One club, every discipline. Whether you have never raced or you are chasing a championship qualifier, there is a session and a group of people here for you.

Group runs, every week
Wednesday evenings and weekend mornings in Hyde Park and Richmond Park, plus UKA-qualified coached sessions at Paddington Rec.

A trail run every month
Out in the Home Counties on the last Sunday of most months – the North Downs Way, Box Hill, the Chilterns, Epping Forest. Eight miles to a half marathon. Members only.

Ride, swim, race
Weekly group bike rides and coached pool sessions, plus an annual training holiday in Lanzarote.

Coached pool sessions
Drills and yardage with Serpentine coaches, Monday evenings at Guy's Hospital and Wednesdays at St Pancras. Most levels welcome if you can swim 100m front crawl.

Last Friday of the month 5k
Our best-loved event — a good quality lunchtime 5k in Hyde Park, open to everyone, every last Friday of the month.

Every pace, every age
Beginners to elite, students to over-65s. Regular socials and volunteering keep the club running — our community matters as much as our results.

Event details
Founded in 1982, still growing
Serpentine started with a group of runners training for the 1982 London Marathon. Today we're one of the largest running and triathlon clubs in Britain — a wide mix of ages, from a few juniors to members in their eighties, but still a friendly, small-club feel. Our roots are in road running, but members now race cross country, track and field, and triathlon and multisport up to Ironman distance and beyond.
